Refrigeration piping work shall be carried out professionally by qualified refrigeration mechanics in
accordance with applicable national and local regulations and in conformance with good engineering
practices required for the proper operation of the refrigeration system.
百尔生产的压缩冷凝机组有较高的洁净度和干燥度,并且系统内部充注了干空气或氮气,可以防止氧化和
湿气及异物的进入。 管道在安装时应格外小心,减小管道安装的时间可以防止湿气或异物的进入。
内部相连的制冷管道的大小不必与机组的出口管道大小一致。 管道尺寸的选择/计算是基于确保最小制冷
剂压降和有效回油最低制冷剂流速。百尔公司可提供相应的管道尺寸计算的技术支持。
水平吸气管与机组连接的时候应有适当的坡度,使油因为重力而自由返回压缩机。1:100 的坡度是比较合
适的。竖直段管道必须使用回油湾及双立管。吸气管道应有保温措施,减小过热影响。
如果在安装时有任何疑问,请向当地的销售代表咨询。
All Centurion condensing units manufactured by Beijer Ref are supplied clean and internally
charged with dry air or nitrogen to prevent oxidation and ingress of moisture or foreign matter. Care
shall be taken during installation of the piping to prevent entrance of foreign matter or moisture by
minimizing the time that the piping is uncapped.
The interconnecting refrigeration pipe size is not necessarily the same size as the outlet on the
unit. The pipe sizes shall be selected/calculated based on the best compromise of minimizing
refrigerant pressure drop and refrigerant velocity to ensure efficient oil return.
Horizontal suction lines shall slope towards to the units to allow the oil return freely to the
compressor by gravity. A 1:100 slope is considered sufficient. The use of oil trap and double risers
may be necessary on vertical sections. Suction line piping shall be insulated to minimize the
superheat effect to the vapour.
If in doubt during the installation, please consult with your local sales representatives
and/or application engineers from Beijer Ref for technical support.

压缩机启动
Compressor Starting
对于较大型的压缩机启动时产生的瞬间起动电流要格外小心。
Care should be taken to establish starting requirements for the larger compressors due to high in-
rush current.
